Real-time video-based audience reaction sentiment analysis

Video data from audience participants reacting to a speaker participation during a conference is obtained. The video data is processed to detect and recognize reactions based on a speaker presentation. Sentiment types are determined for the recognized reactions in view of a context of the speaker presentation. An engagement level is determined based on aggregated sentiment types for the audience participants. A real-time recommendation output is presented based on the engagement level. The real-time recommendation output provides suggestive actions for the speaker participant based on a positive or negative engagement level.
